k Solutions Supported by ClassPad (TRUE, FALSE, Undefined, No Solution,
const, constn)
Solution
TRUE Output when a solution is true.
FALSE Output when a solution is false.
Undefined Output when a solution is undefined.
No Solution Output when there is no solution.
∞
Infinity
const Constant displayed as const(1) when any
value that is a constant is included in the
solution. In the case of multiple constants,
they are indicated as const(1), const(2),
and so on.
constn Constant displayed as constn(1) when the
